Description

Gait rehabilitation training
Technical field
The utility model relates to one kind can carry out the training airplane that simulation gait rehabilitation is taken exercise.
Technical background
In recent decades, due to natural calamity and traffic accident etc., the quantity that limbs of patient is damaged increases greatly It is high.Largely leave light or heavy sequelae.In addition, during society is gradually aging, the body of the elderly Voxel matter difference is easy to cause cardiovascular and cerebrovascular disease and the nervous system disease, this kind of sufferer majority with hemiplegia symptom, and The common feature of these diseases is the obstacle that all there is limb motion.It, can be with recovered part muscular strength, even by using this product The state of normal person can be restored to.
Not only volume is larger but also expensive for current existing gait rehabilitation instrument, therefore market popularization degree is not high, Needless to say family uses.And by above-mentioned gait rehabilitation instrument, patient may be implemented to carry out gait simulation anywhere or anytime Rehabilitation training.Therefore, the main innovation point of mechanism is organically knot that the auxiliary of the gait rehabilitation of connecting rod and wheelchair is advanced Altogether, help patient in common traveling process also can the recovery from illness well to the lower limb of oneself perform physical exercise.
Summary of the invention
The utility model will overcome the shortcomings that prior art, provide and a kind of small in size, wieldy carry out simulation step The training airplane of state reconditioning.
Gait rehabilitation training, including vehicle frame are equipped with rear-wheel and front-wheel, cushion on vehicle frame, after the rotation axis of rear-wheel is Sprocket shaft is equipped with rear sprocket wheel on rear sprocket shaft, chain is housed, the both ends of preceding sprocket shaft respectively have one between rear sprocket wheel and preceding sprocket wheel A second crank, second crank at the both ends of preceding sprocket shaft is all perpendicular to preceding sprocket shaft and reverse phase setting, the end of the second crank It is defeated with multi-connecting-rod mechanismIt is hinged to enter end, the output end and pedal of multi-connecting-rod mechanism are hinged;
Multi-connecting-rod mechanism includes upper triangular structure, quadrilateral structure, lower triangular structure, upper triangle knot from top to bottom Structure is hinged and is formed by No. four bar, No. five bar, No. six bar, and quadrilateral structure is by No. second bar, third bar, the 4th Number bar, ride on Bus No. 11 bar composition, lower triangular structure are hinged and are formed by number one bar, No. second bar, the tenth No. two bar;
The be hinged lower extreme point of the lower triangular structure to be formed of number one bar, the tenth No. two bar is the defeated of multi-connecting-rod mechanism Outlet;
The input terminal of multi-connecting-rod mechanism is hinged and is constituted by the end of No. nine bar, No. eight bar, No. ten bar, and the 9th The other end of number bar is hinged on the first hinged-support on vehicle frame, the other end of No. eight bar and the upper extreme point of upper triangular structure Hingedly, the other end of No. ten bar is hinged on the hinge joint of ride on Bus No. 11 bar, No. second bar, the tenth No. two bar;
No. six bar, No. four bar, ride on Bus No. 11 bar, the first crank are all hinged on the second hinged-support, the first crank The other end is hinged on the first hinged-support.
Further, the front end of cushion is hinged on vehicle frame, and the rear end of cushion connects electric pushrod.
The utility model is mainly made of supporting mechanism, walking mechanism, transmission mechanism and gait executing agency etc., with wheel Chair is entire mechanical basis, by the way that connecting rod is carried out the simulation that gait is realized in certain combination connection, then benefit using bearing etc. The power of the wheelchair of traveling is transferred to connecting rod with sprocket wheel, when someone pushes wheelchair, power is from other people.Wheelchair quilt When promotion, wheelchair rear wheel is rotated with moving axis and the sprocket wheel being fixed on axis, passes through the wheel disc and song of chain conveyer power to front Handle, crank be separated by 180 ° rotation drive link mechanism so that pedal with simulate people's gait track move, drive lower limb into Row gait rehabilitation.The main innovation point of mechanism, which is to advance the auxiliary of the gait rehabilitation of connecting rod and wheelchair, organically to be combined Come, help patient in common traveling process also can the recovery from illness well to the lower limb of oneself perform physical exercise.By using this Product, can be with recovered part muscular strength, or even can be restored to the state of normal person.
The utility model is divided into three modules, respectively execution module, transmission module and drive module.Execution module is divided into Shaft portion and elevating cushion.Connecting rod is the core of design, can simulate the movement of gait;Elevating cushion can make patient Lower limb bear weight, help to improve rehabilitation efficacy.Transmission module is the part that rear wheel is transferred to front link structure, It is made of sprocket wheel, chain, wheel disc.
(1) execution module:
A) shaft portion:
In entire execution module, 12 connecting rods and crank are combined, and deliver power to former dynamic connecting rod by sprocket wheel, The dynamic connecting rod of original moves in a circle, by this 12 bars and crank it is hinged made of two effective triangles (by number one bar, second Effective triangle of bar and the 12nd bar composition, forms another effective triangle by the 4th bar, the 5th bar and the 6th bar), the One crank and a quadrangle (being made of the second bar, third bar, the 4th bar and the 11st bar) transmit power to distal point, To realize the simulation of track.
B) elevating cushion:
Cushion is connected with two push rods, is fixed in wheelchair frame by hinge, when controlling push rod by controller, sits Pad meeting lifting angle, so that angle becomes larger between patient's thigh and calf, body approaches stance, and gradually stress reaches human body to patient's lower limb 2/3 weight, posture transformation gradual so not only alleviates the pain of patient, but also facilitates the better rehabilitation of patient.
(2) transmission module:
In transmission module, advanced by attendant propelled wheelchair, and then the power of rotation is passed into wheelchair rear wheel axis, it is fixed Rear sprocket wheel on axis is also with rotation, sprocket wheel rotation before driving under the action of chain, while the connecting rod being connected with preceding sprocket wheel Former lever can carry out circular motion.
